26 Claims.
(01. 164-411)
This invention relates to a machine for punch
ing perforations in cards, such as address bear
ing stencils and printing plates, employed in ad
the perforating of such selected zone.
Another object of the invention is a card per
forating machine comprising an index plate hav
ing zones corresponding in position and number 01
to the perforation receiving zones of the card,
punching mechanism including a pointer mov
able into register with a selected zone of the plate
for positioning a punch in register with the cor
responding zone of the card,‘ and means con
dressing machines in the manner described in
;.5 the copending applications of Harmon P. Elliott,
Serial No. 69,803, ?led March 20, 1936, and Serial
No. ‘75,118, ?led April 18, 1936.
Such addressing machines are arranged to re
cord on a record sheet, usually concurrently with
10 the recording of an address, selected items of
trolled by the pointer for effecting a punching
operation of the mechanism.
A yet further object of the invention is the
statistical information denoted by the relative
position of marks formed on the record sheet un

adapted to have a perforation when such item
20 is to be indicated on the record sheet.
vOne of the objects of the present invention is
an improved machine for selectively perforating‘
the cards, as the stencils or other printing de
vices, for this purpose.
In a copending concurrently ?led application
25
of’Harmon P. Elliott, Serial No.’ 84,150, a card
perforating machine is disclosed utilizing a plu

As illustrated in Fig. 3, the card or printing de
vice comprises a stencil l6 having in one portion
a stencil sheet l8 bearing an address 20, and in
another portion a series of zones 22, the different
positions of which denote different statistical
items. . The zones 22 are arranged in horizontal
and vertical columns and are consecutively num
bered as at 24.
‘
The stencil herein shown has provision for one
hundred and ?ve (105) zones although the pre
cise number is of no particular importance to the
present invention. Each zone is preferably pro
vided with a mark as a small circle 26 printed
thereon for indicating the location of a possible 50
perforation. When the stencil is perforated by
the machine of the present invention such marks
26 are not necessary.
They are desirable, how
ever, for indicating the location of a perforation

The stencil is adapted toreceive perforations
28 in selected zones. The perforations control
the passage of marking members through the
stencil and into pressure applying relation with
III a record sheet thereunder for the purpose of
‘lower end of the rod is connected to an eccentric
strap 58 operating on an eccentric ll’ll) journalled
loosely on a shaft 502. Said shaft is rotatably
supported in bearings Hi4, see especially Fig. 1,
and is continuously rotated from the continu
making a mark on the record sheet in a location
corresponding to the location of a perforation,
ously rotating shaft 36 of the’ power mechanism
by means of pulleys W8, W8, and the belt H0.
The marks thereby indicate by their position on
the record sheet the items of information de
noted by the perforated zones of the stencil.
The machine for perforating the stencil com
prises a table 30, see Figs. 1, 2 and 3, supported
on uprights 32 and having its operative parts
The eccentric 805 is adapted to be connected
with the shaft N32 for rotation therewith by
operated by a power device 34, now common in
the art. The power device includes a continu4
ously rotating shaft 36 and an intermittently
rotating shaft 38, the latter shaft being arranged
to make one complete revolution per operation
and then to stop. The rotation is under control
20 of a pedal 40, which when depressed and subse
quently released effects one complete rotation of
the shaft 38.
A collection of the stencils l6. preferably with
the addresses 20 thereon is contained in a holder
‘i2 disposed at one end of the table 3!) and in reg
ister with the entranceof .a stencil track formed
by a pair of horizontally spaced guide rails M
which are spaced above the table.
The succes
sive lowermost stencils of the holder are advanced
30 in successive order into and along the track by
a reciprocating pusher 46. Said .pusher is recip
rocated by a vertical lever>48 pivoted to the frame
of the machineat 50 and connected to the pusher
by a link 52. The lever is reciprocated by means
35 including an eccentric 54 which is ?xed to and is
rotatable with the shaft '38. The eccentric has
an eccentricstrap 58 that is swiveled to the end
of a pivoted arm 58 that reciprocates a leverr??
bearing against the lever 48 and connected there
40 to through a tension spring 62. The arrange
ment of the arm 58, lever 60' and spring 62 issuch
as to. permit reciprocation of the parts as a unit
under ordinary conditions but'to permit the lever
to stop reciprocation if astencil or printing de
45 vice should jam in the track‘ M. The perforated
stencils are discharged from the end of the track
into a stencil receiver 64.
'
The successive stencils rest momentarily sta-.
tionary in the middle portion of the track where
they are operated upon by the punching or per
forating mechanism. Said mechanism includes
a bracket 66 ?xedto and upstanding above the
table 30 alongside and in the rear of thestencil
track. Said bracket is provided with a-pair of
55 parallel bosses 68 in which apairof vertical rods
‘H! are reciprocable. A punch operating member
12 is ?xed to the upper ends of the rods 10- by
means including nuts 74 .and reciprocates with
the rods.
Said member 12 is in the form of a
60 ?at plate which is positioned above and overlies
substantially completely the entire perforation
receiving zones of thestencil.
.
The lower ends of therods below the table are
connected by a plate 18. The rods are recipro
65 cated by toggle mechanism which includes a
bracket 88 ?xedto said plate 18 between the rods.
A pair of toggle links 82 are pivoted at 84 to. said
bracket .and have their upper ends disposed .be
tween and pivotally connected at 86 with the
short arm .88 of a bell-crank lever. Said bell
crank lever is pivoted on a shaft 90 carried by
a bracket 92 ?xed to’ the underside of the table
3!]. The long arm 94 of said bell crank lever. ex
tends rearwar'dly of the machineiand is pivotally
75 connected to the upper end of a rod 96. The
means of a ratchet Hi2 ?xed to the shaft on one 10
side of said eccentric. A collar H4 ?xed to said
shaft on the other side of said eccentric serves
to hold said eccentric from axial displacement.
Said ratchet l i2 is provided with a series of teeth
i it, four teeth being here shown. Said teeth are 15
adapted to engage a pawl H8 ?xed to a shaft
E28 pivoted in and extended through the eccen
tric. Said shaft has an arm I22 ?xed thereto on
the other side of the eccentric which is engaged
by a tension spring H24 that continually biases 20
said pawl for‘movement towards the ratchet.
‘When the pawl is engaged with a tooth of the
ratchet the. ratchet and eccentric are rotated
conjointly. When, however, the pawl is disen
gaged from a ratchet tooth the eccentric remains 25
stationary with the eccentric-at the top ‘of. its
stroke. The reciprocation of theeccentr'ic serves
to straighten andcollapse the operating toggle
consisting of the links 32 and the short bell crank
arm 8% and thereby reciprocates the punch oper v30
atingplate lfitoward and away, from the stencils.
The engagement of the pawl vI N3 ‘with and its
disengagement from the ratchet HZis e?ected
by means of an electromagnet 126. carried'by
the plate l3 and having an ‘armature or core 35
i253 movable into-and out of the magnet. Said
core is connected to and reciprocates a slide bar
I39 which slides in a bracket I32 ?xed-in the
under side of saidplate, l8 andrhasits rear end
disposed in the path of rotation of the latch 40
i it. A tension spring 1344 is connected with said
slide bar we and serves normally to maintain the
slide bar and the armature in a retracted posi
tion. In this position therear end of ‘the slide
bar can be engaged by the latch 0 it ‘as it rotates. 45
The operation is such, that the. rotation of ‘the
eccentric Idisc see with the latch in engagement
with the slide bar, and also the upward movement
of the bar, causes the withdrawal of the latch
from engagement with a ratchet tooth,_thereby
freeing the eccentric‘ from the vcontinuously ro
tating shaft Hi2 and holding'the’eccentric and
the mechanism associated therewith from further
movement. When, however, the electromagnet
50
£26 is energized thejarmature or core ‘I23 'is
moved to‘ retracted position ‘and the end of the
slide bar ‘H39 is pulled out from‘ under the nose
of the latch H8. The latch springil'2llfthen be
comes operative to swing the latch into-engage
ment with the ratchet to cause ~the latch to ‘be
engaged by a ratchet tooth and vcarried around
therewith. The electromagnet is intended to' be
but momentarily energized so‘ that the slide’ bar
6,0
is positioned in‘ the path of rotation of they latch
before the'latch has made a complete revolution. 65
Hence the slide bar 'is in position to be‘engaged
by the latch and to cam it out of engagement
with the ratchet upon the completion of a single
revolution, thereby ‘to stop further reciprocation
of the mechanism.
The bar‘ also holds the
mechanism stationary with the eccentric‘at‘the
top of its stroke.
’
'
'In accordance‘ with this invention a single
punch device H4 is employed. Said punch de
vice is carried by a system of copying linkages
3
2,127,681
and particularly a pantograph system of pivotally
connected links comprising the long punch car
rying link I76, and the shorter link H8. Said
links are maintained in parallel relation by a pair
of long and short cross links I80 and I82, respec
tively, which are pivoted to the links [l6 and I78.
The inner end of the link I18 is secured to a
?ange M30 located in a recess of the table 36
formed on the upper end of a relatively long
stud shaft I85 journalled in a bearing block E88
secured to the underside of the table, see espe
cially Fig. 6. This arrangement provides a steady
pivotal support for the pantograph. The free
end of the lever I80 is terminated in a pointer

pointer, punch and axis of the pantograph link
age are in the same line and consequently the
punch is caused to faithfully follow the movements of the pointer.
The rear part of the punch carrying arm I'IB is
bifurcated, the furcations I'I?a and I'ltb being
on opposite sides of the stencil track All. The
furcation I'l?b at its rear end where it underlies
the stencils in the track has a generally cylindrical
punch passage H2. The upper furcation i'?o.
The pointer I90, see especially Fig. 5, comprises
a bushing 2I0 secured in and upstanding above
the free endof the link I80. A plunger 2I2 is
reciprocable within said bushing and has a con
ical or tapered lower end 2M adapted to be de- i
pressed into seating engagement with any recess
208 of the index plate. Said plunger has an en
larged head or flange 2I6 at its upper end ‘which
is located movably within a cap 2I8. A heavy
helical spring 220 is located within the cap be
tween the upper end thereof and the head 2H5
and a lighter helical spring 222 is located under
said head 2 I6 and on the end of the bushing 2 I0.
The cap is provided'with a vertically elongated
slot 224 within which a screw 226, screw—threaded
into the bushing, is located whereby to limit the
vertical displacement of the cap. The spring
L15
222 normally holds the plunger 2I2 and the vend
cap in the uppermost positions thereof with the
bottom wall of the slot 224 against the limit 1.2.0
screw 226.
By pressing the cap 2 I8 downwardly i
the light spring 222 yields causing the end of the
plunger 2 M to enter and seat in a depression 208
of the index plate in register with the plunger.
The cap 2IB carries an axially located circuit 12.5
controlling
contact pin 228 which is axially mov
carries at its rear end the major part of the
able within the plunger 2I2 and normally is held

prises a barrel I94 which is fixed in and upstands by the spring 220 with its lower end withdrawn
above the rear end of said furcation H60; and within the lower end of the plunger. When, how~
